FUELHEATER.

1.1 oaoesl To all c/110m it may concern Be it known that I, THOMASTAYLOR, a citizen of the United States, residing at Kenton, in thecounty 'of Hardin and State of Ohio, have invented certain new anduseful Improvements in Fuel-Heaters, ofwhich the following is aspeciiication.

The present invention relates to an improved fuel heater to be used -inconnection with and attached to an internal combustion or vapor engine.`

The primary object of the invention is the provision of means forheating kerosene and air as fuel for vapor explosive engines, and inorder to accomplish this purpose economicallyand conveniently, I utilizethe exhaust gases from the explosive engine as they pass through theheating device to bring the kerosene to almost the boiling point and'also to he'a't'the air to a very, high temperature and these conditionsprovide a more eiiicient mixture for fue than that obtained fromgasolene. In cnnection with the attachment I utilize ajgasolenecarbureter for the initial combustion in the engine, and after theengine is running, and the exhaust' therefrom has heated the kerosene sothat it may be thoroughly volatilized, the gasolene is used exclusively.

In the accompanying drawings `I have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have practical application of the principles of theinvention.

Figure l is and an accompanying carbureter, the latter being shown asconnected to an engine, and the former connected with the exhaust fromthe engine. Fig. 2 is a sectional view of the carbureter on line 2 2 ofFig. l. Fig. 3 is a transverse sectional'view showings. portion of thefuel heater and illustrating particularly the kerosene coil with itsends leading to the fuel tank and to the carbureter.

In the preferred embodiment of my invention I employ the two heads 1 and2 between which are fixed the outer shell 3 and the inner .casing e',both cylindrical in form andv spaced apart to form a hot air chamber 5which. is open to the atmosphere through the lower end of the shell. Theheads ofthe heating drumare erfoto receive a pipe connected with theexhaust of the engine, and

Sleeves or hollow bosses 15, integral With the casing 4;are located in which the pipe ends pass, and lock nuts-16, 1G, areemployed to make a secure fastening of the pipes at the outside of theshellk 3. The carbureter 4illustrated in Fig. 2 is connected with th'ehot air space 5 through the opening in the shell and the short flanged'pipe 17, and the carbureter is secured to the heater drum and engine bymeans of the iianges 18 and -19 and suitable bolts. The carbureter'cylinder 20 is open to the passage of heated air fromthe heater drum tothe engine, but the trolled and regulated by means'of afturn` plug orvalve 21 located in the open lower end of the cylinder and revolubletherein. This valve is formed with an annular groove 22, and by means ofthe bolts 23 in the wall of the cylinder which enter the groove, theplug is held against displacement and may be turned by the handle ,24.The valve is cylindrical in cross'sectin and is cut away or cupped at 25to provide communication between the short pipe 17 and the interior ofthe cylinder 20. It will be understood that by revolving theirecessedplug the area of communication may be increased or decreased. The heatedkerosene passes from the tank 26 and the fiow of sprayed li uid iscontrolled by the needle valve 2 which is threaded in the top or cover28-of the cylinder, and an overiiow pipe 29is used to carry supply tankany excess of kerosene 1n the tank 14. A. second needle,

back tothe fuel valve 30 controls the supply of gasolene in the cylinder20, from the gasolene tank 3l which is equipped' -'with the usualiioat32 and valve 33 and inlet pipe. By extending. the tube or outletreceives a supply from the pipe 8 withits perforations entirely throughthe space 5, through 14 through the 'tube passage of the air is conthecoils and far into the hea-ting or exhaust chamber of the casing 4, thefull heating properties of the gases of combustion as they are exhaustedfrom the engine,

The kerosene in the coils is heated by the gases as,

-they pass through the casing 4f and the perforated pipe 8, and the airfor-fuel passing through the space 5 is heated also and passes through.the plug valve 21 to the cylinder 20. The vaporized kerosene in itsheated condition, and the heated air are eommingled in the cylinder orcarbureting chamber 2O and pass from there into the cylinders of theengine. By thus heating the kerosene, which normally is less volatilethan gasolene, and heating the air, a mixture is produced which providesa more powerful eX- plosion than is obtained from gasolene, acomparatively tained, and the objectionable soot or smoke which is soinjurious to the engine, spark lug, etc., is eliminated The attachmentmay be made to form a Copies of this patent may be obtained for fivecents. each, by addressing the Washington, D.

Having thus fully described my invention, what I claimv is l. In a fluidfuel heater the combination of a perforated shell forming an airchamber, an imperforate casing Within the shell and a coil in the casinghaving inlet and outlet, an inlet pipe to the casing, and a perforatedoutlet pipe extending from one end of the casing to near the otherendthereof, whereby the coil is heated by gases flowing throug'lithe casingto the outlet pipe.
